Enzyme Information

2.7.7.48
RNA-directed RNA polymerase.
based on mapping to UniProt C0MHL9
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
-!- Catalyzes RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. -!- Can initiate a chain de novo. -!- See also EC 2.7.7.6.
3.6.4.13
RNA helicase.
based on mapping to UniProt C0MHL9
ATP + H(2)O = ADP + phosphate.
-!- RNA helicases utilize the energy from ATP hydrolysis to unwind RNA. -!- Some of them unwind RNA with a 3' to 5' polarity, other show 5' to 3' polarity. -!- Some helicases unwind DNA as well as RNA. -!- May be identical with EC 3.6.4.12 (DNA helicase).
3.4.22.28
Picornain 3C.
based on mapping to UniProt C0MHL9
Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly.
-!- From entero-, rhino-, aphto- and cardioviruses. -!- Larger than the homologous virus picornain 2A. -!- Belongs to peptidase family C3.
